 Tank Float
Author: Mickel

I have Fluid Master brand water filler valves in the toilets of my 24 unit apartment building. Occasionally the barrel float cannot push up the valve to shut off the water in the tank. I have discovered it's NOT the barrel but rather the valve gets stuck. If I use my finger I can make the valve shut off easily even with a slight touch.

Is there a way to lubricate the valve to restore the valve to make it shut off again or do I just replace the entire thing. I am open to any suggestions.

You can change out the rubber in the top of the Fluidmaster. It is a valve and seat. sometimes that gets worn and will not function correctly.
